It has a variety of video sequences which can be programmed by day, night or holiday cycle. On the alarm side, the E-SM328 provides 32 alarm inputs and 8 relay outputs. Events can be initiated on alarm input including moving a PTZ camera to a preset position or starting a particular monitor sequence. For privacy reasons, the video inputs can also be masked on fixed cameras.

The matrixs two RS485 lines are for communication with the E-SM16 advanced multiplexer or for telemetry connection to a PTZ camera or speed dome. They can also be used to connect additional matrixes in a slave/master or parallel setup.

With the master/slave configuration, the master matrix can accept max 4 inputs from each slave matrix. In a parallel setup, up to 9 matrixes can be connected. A keyboard connected to the master is able to control all cameras connected to any of the slaves or to the master.

The E-SM328 is fully controllable via the E-DCJ, E-DCK or E-DCT control keyboards. It can also be controlled via the RS232 port from a PC.
